Need to format the boot partition too which is not an option unless you choose "wipe all partitions but sd card" (i.e. "superwipe").

Attached is a superwipe script .zip that Newt made. Flash it just like a ROM before flashing your next ROM.

Here's the actual script:

show_progress(0,0);

ui_print("");
ui_print("");
ui_print("");
ui_print(" _______ __ __ ______");
ui_print("| | |__| |--.| __ \.-----.--------.-----.");
ui_print("| | | < | <| _ | |__ --|");
ui_print("|__|_|__|__|__|__||___|__||_____|__|__|__|_____|");
ui_print("");
ui_print("=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-");
ui_print(" Super Wipe Script!");
ui_print(" Brought to you by Newtoroot");
